3 Claims. (Cl. lOl-27) vvOur present invention relates to a hot stamping device which is primari-lyintended for stamping,` imprinting or embossing plain, colored, lustrousfor metallic foil letters, monograms, designs, insignia,'etc., upon articles of' stationery'such as writingl paper, announcements, cards and the like. Itmay, however, also be used and is adaptable for similarly treating articles of `merchandise made ofpaper, libre, leather, textile and analogous materials. i 'A t l f The' primary object of our invention is to pro-V vide'a'device of the character described whichis exceedingsimple in construction and operation 1@ sothat aniinskilled person can Yeiliciently operate ita'fter afew minutes instruction and which can be manufacturedand sold at a price which should enable everyfstatibnery" and'leather goods dealer toacduire one.4 A further object is to provide .adevice ofthe character'cklescribed wherein the type or dies"arevisiblycarried by the device in front ofthe operator-so thatthe's'etting up and resettingfbf said type or dies can be accomplished inv thelea'st possible timewithout the operator u' vide van improved supporting means for` the color strip" or ribbon c'arrying'the imprinting inkfor mtalfoil andV automatic feeding means therefor,

A'.I'st'ill"further object is to'providea novel readilyV renewable'cushioning element for the type or die stamped.

:The foregoing and other objects of our inventionV will be ap'parent AfromrtheY detailed descrip- .i tiorifoi'the device which followswhen considered 3 inF conjunctionwith the accompanying drawings,

whreinlz 'v Figure I1' is a irontV elevation ofthe device embodyingour invention,` parts thereof being broken.

tion A2a having a transverse recess 3a therethrough foraccininodating. heating means preferably in the-forrriofan electric-resistant element C which is rerno'vabl'yf carried thereby. The front and rear sideseofthe member2a are inclined inwardly fromI the base thereof as indicated at id toprovide a supporting and. guiding means for apalette or typeholding means D. `A A Thefpaflette D'is formed with a dovetailed reces`e""or"s1`id"ewayfor"'en'gaging over the tapered sides 4a and is formed on its under side with a when! making the impression on the article being socket member d within which type elements or dies E may be suitably held and clamped in position by a clamping screw 2d. In its front wall, the palette D carries a handle 3d the inner end of which screw-threadedly engages through said wall and is adapted to engage the member 2a to clamp the palette in position thereon.

The base member B at its top supports a table b and depending from said table and extending centrally through said base member is a stud 2b formed with a rack 3b. Transversely extending through an opening in the base B is a shaft F adjacent one end of which is provided with a pinion f in engagement withthe rack 3b. To the opposite end of the shaft F there is connected an operating lever 2f which is held to the shaft by a clamping screw 3f.

Mounted on the table b is a platen G which is movable upwardly toward the palette D as the operating handle 2f is moved downwardly. On its under face the platencarries a depending pin y which extends through an 'opening in allug 4b whereby the Vplaten `is held against `rotational movement with respect to the base. At the lower end of thepin g is a washer 2g held thereon by a screw 3g and encircling said pin between said washer and the under-face of the lug 4b is a helical spring 4g which is adapted to return the plat en downwardly and move the operating lever 2f upwardly upon the completion of an imprinting operation. At the rear of the platen G there are mounted two plates 5g each of which carries a stud or pin member 6g which extends in parallel relation over the top face of the platen.

Mounted upon the top face oi the platen and adapted for adjustment forwardly and rearwardly with respect thereto is a gauge bar Hwhich at .each end is formed with an opening through which one of the pins 6g extends, which pins function to guide the gauge bar in its movements. To x the gauge bar in any adjusted position upon the platen thumb screws h extend through the ends thereof for. clamping engagement with the pins 6g. A second gauge bar H is mounted to slide in a guideway 2h on the under face of the platen and is adapted to be held in adjusted position by a clamping screw 3h. Spring clips 4h, are carried by thegauge bar H andare adapted to receive and hold the paper to' be' stamped while the platen is being raised and lowered.

Supported on the underside of. the platen through the medium of a bracket J and a pin 7 carried thereby is a roll of heavy paper 2i which is adapted to engage over the face of the platen below the type or die and function asa cushioning element therefor when makingan impresesion` on the article beingV stamped. In order thatwthe topfface of the platen may retain its smooth' surface conditionfor accommodating the article to be stamped itis formed with a depression '7g having a depth substantially equal to the thickness of the cushioning strip 3j from the roll 27'. To accommodate the cushioning strip 3g the platen is formed with guide slots 8g and 9g and to hold said strip within said depression any suitable means may be employed, for example a sheet of paper may extend across the strip be fixed to the platen. The free end of the cush-` ioning strip which extends through 4the slot 9g -may also be held if desired by any suitable means or may be left free for engagement by the ngers of an operator to pull the same over the platen to present new portions of said strip belowthe stamping die when required. 4

Secured to the top bar of the C-shaped frame? is a carrying member K, near one end of which is mounted a spindle lc extending forwardlythere from uponwhich in turn is mounted a disk 27C, and'aroll of imprinting material L which may be of*A any desired character which will permit a transfer of colored ink or metallic f'oil'therefrom to an article being stamped under the influence of heat` and pressure. To provide lthe necessary frictional resistance to said roll Lto permit'unwinding thereof under tension a secondv disk 37c'is mounted on said spindle and held in frictional engagement against the roll L by any suitable means, for example, a clamping ring 47a. At the opposite end of the member K upon a depending lug thereof is mounted a spindle 5c upon which in turn is rigidly mountd a friction roller M. In superposed relation to the-roller M isa second friction roller N carried by an arm 6k p ivoted at 7k, saidV roller N being held against the roller M under the tensionof a spring 87o, one end of which is connected to an end of a bar 6k and the other end of which is detachably secured to a pin 9k. y l

,Also `carried bythe spindle 5k ,is a ratchet wheel O, movement of which by a gravity activated pawl P causes movement of the roller M to draw the color stripl from the roll L between the rollers M and N. `The pawl P is pivotally mounted at p to'one end of a linkQ, the other end of which is also iixedly'mounted on the vspindle 5k. For moving the. link Q and with itv the ratchet wheel `O there is provided arod R, one end 1' of which` is fxedto the platen G and the otherend 2r of which is, pivotally connected to the link Q intermediate its ends. For varying the throw of the pawl Pthe link Q may be provided with several openings q to which the end 21 of the rod R may be connected. For rendering the feeding means for the strip Z inoperative, it isrmerely nec# Y essary to throw the pawly over on its .pivot as shown in dotted lines in Fig. 3.

Mounted upon the member K in inclined rela? tion to the front ofthe rdevice isa type case S Iconsisting of a base element s and a top `plate,

' provided ,for specific dies, insignia, etc.

The horizontal rows are.

die is positioned within the palette D and held therein by the clamping screw 2d. The palette is then mounted on the member 2a and clamped thereon through the operating handley 3d. The palette and its type are then heated by the electric heating element C by turning on the current therethrough. The color strip Z is then fed from the roll L around the guides 6g and then up between the friction rollers M and N. The cushioning strip 37' from the roll 2y' is threaded through the slot 8g in the platen and disposed in the recess 'Zg and held therein as hereinbefore described..` The gauge bar H is then adjusted for the 'particular size sheet to be stamped and upon feeding such sheet to the platen under the clips 4h and moving the platen upwardly into contact with the heated type E the colorv medium or metallic foil from the strip Z will be transferred to the sheet, whereupon by releasing the operating handle 2 f. the platen is returned to its lower position by the coil spring 4g. As the platen recedes, v the strip Z is fed a predetermined amount by the ratchet and pawl construction. These operations are then repeated until the `particular quantity of paper is stamped. The end 9g of the cushion# ing strip is then gripped to draw a length of paper across the platen to present a fresh cushioning surface to the type for the next job. To perform the operation upon a second job the operator without' leaving his station can quickly reset the palette' from the type .case in front of him.

While we have shown and described a preferred' embodiment of our invention it is'to be understood that changes may be made therein without departing from the'spirit thereof.
